Bathtub hand rest

ABSTRACT

An improved structure for a bathtub hand rest comprises a pair of clamps, a hand rest and fasteners. Each of the clamps has two plates with their horizontal sections overlapped to each other and a positioning bolt laterally penetrating vertical sections extending from the two overlapped sections. The fastener is locked to the inner wall of each end of the hand rest with inner threads. The periphery of the fastener is provided with outer threads and a fastening hole in the center of the fastener. The clamps are held against the bathtub, and the fasteners are screwed to both ends of the hand rest. Positioning bolts penetrate through the clamps and locked to the fastening holes in the fasteners for the hand rest to be secured to the clamps.

BACKGROUND OF THE INVENTION

[0001] (a) Field of the Invention

[0002] The present invention relates to a bathtub hand rest, and moreparticularly to one with excellent strength and well secured to thebathtub.

[0003] (b) Description of the Prior Art

[0004] As illustrated in FIGS. 3 and 4 of the accompanying drawings, ahand rest generally available in the market essentially comprises twosets of clamps (A) and fasteners (B) and a hand rest (C). The hand rest(C) is a hollow U-shaped tube. Each of the clamps (A) comprises twoL-shaped plates (A1, A2) with their lateral sections overlapped to eachother. A positioning bolt (D) to laterally pass through the plates (A1,A2) and secured to a cap (D1) to be fastened to the edge of a bathtub(E). The fastener (B) each built in the end of the hand rest (C) isprovided with a threaded section (B1) both ends respectively riveted toa stopper (B2). Multiples of gaps (B21) are provided on the periphery ofeach of the two stoppers (B2). Upon assembling as illustrated in FIG. 5,the fastener (B) is first pressed into the end of the hand rest (C). Asthe outer diameter of the stopper (B2) is slightly greater than theinner diameter of the hand rest (C), the stopper (B2) can be firmlysecured inside the hand rest (C). Another positioning bolt (F)penetrating through the bottoms of the L-shaped plates (A1, A2) of theclamp (A) and locked to the threaded section (B1) of the fastener (B) tomerely indirectly lock the hand rest (C) to the clamp (A).

[0005] However, the prior art has the following defectives:

[0006] 1. A special mechanical tool must be used to force the fastenersinto the hand rest making the assembly awkward and the appearance of thehand rest is easily damaged.

[0007] 2. The fastener is essentially pushed against to the inner wallof the hand rest by packing. That is, both of the hand rest and thefastener are held in position by pressing against each other, failing asecured attachment. Frequently, when the hand rest is held atinclination, the hand rest could be just be pulled off leaving thefastener and the position bolt on the clamp. Such poor structuralstrength is very dangerous to a user of the bathtub.

[0008] 3. The central line of the stopper each riveted to both ends ofthe fastener is difficult to be aligned to the center of the body of thefastener. As a result, the fastener gets misplaced when it is pressedinto the hand rest, thus the threaded section inside the fastener ismisplaced to serious affect the subsequent assembly works.

SUMMARY OF THE INVENTION

[0009] The primary purpose of the present invention is to provide animproved ark structure of a hand rest for a bathtub that is providedwith high structural strength. To achieve the purpose, the presentinvention essentially comprises a pair of clamps, a hand rest andfasteners. Wherein, Each of the clamps comprises two L-shaped plateshaving their horizontal sections overlapped to each other, a positioningbolt laterally penetrating the plates curved from the two overlappedplates and a slip-proof pad is each adhered onto the inner walls of thetwo plates.

[0010] The inner wall to both ends of the hand rest is threaded to lockup the fastener. Outer threads are provided on the outer periphery ofthe fastener and a hole for fastening is provided at the center so thateach clamp holds with its plates against the periphery of the bathtub.Then the fastener is engaged to the end of the rest hand, and anotherbolt penetrates through the bottom of the clamp through the hand restand fastened in the fastening hole.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0016] Referring to FIG. 1, the present invention essentially comprisesa pair of clamps (1), a hand rest (2) and fasteners (3). Each of theclamps (1) comprises two L-shaped plates (11, 12) with their horizontalsections overlapped to each other. Both of the horizontal and verticalends of the plate (11) are respectively provided with a hole (111, 112)while a slot (121) is provided on the horizontal section of the otherplate (12). The front end of the horizontal section of the plate (12)extends downward and curves to form a fastening plate (122) provided ahole (123) on its vertical side. A positioning bolt (13) is used tolaterally penetrate through the hole (112) and the hole (123), and thenis locked by a nut (131) to connect both plates (11, 12). A slip-proofpad (14) is respectively attached to the inner sides of both plates (11,12) and to the bottom of the fastening plate (122).

[0017] The hand rest (2) has its both ends provided with inner threads(21) to the inner wall.

[0018] Each of the fasteners (3) is a cylindrical member compromisingthe inner periphery of the hand rest (2). The outer periphery of thefastener (3) is provided with outer threads (31), a fastening hole (32)with inner threads penetrates through in the center of the fastener (3)and multiples of ribs (33) are provided to reinforce the fastening hole(32).

[0019] Now referring to FIG. 2, the two plates (11, 12) from each set oftwo clamps (1) hold against at where appropriately on the periphery of abathtub (4) depending on the lateral length of the hand rest (2). Thepositioning bolt (13) is locked to the plates (11, 12) so that the clamp(1) is firmly adhered to the bathtub (4) with the slip-proof pads (14)respectively attached to both inner sides of the plates (11, 12) and tothe bottom of the fastening plate (122). The outer threads (31) of thefasteners (3) are engaged with the inner threads (21) in both ends ofthe hand rest (2). Another bolt (15) penetrates vertically from thebottom of the clamp (1) in the direction relatively to the hand rest (2)to expose from the slot (121) and the hole (111) of the clamp (1) and issecured in the fastening hole (32) of the fastener (3). Therefore, thebolt (15) is firmly fastened to both ends of the hand rest (2) for thehand rest (2) to be secured to the clamp (1) for use with the bathtub(4).

[0020] In practice, the hand rest (2) and the fastener (3) arecompletely screwed to each other, while the fastener (3) and thepositioning bolt (15) are further screwed to each other and secured ontothe clamp (1) to provide a much reliable structural strength than thatachieved by packing as seen in the prior art. Furthermore, the presentinvention is easier to be assembled on site.

[0021] As disclosed, the present invention by offering a bathtub handrest with compact and reliable structure to avoid accidental breakage.
